It may take days for a coroner to positively identify a Northern California man who was fatally shot by a sheriff's deputy after he fired more than 100 rounds at officers and neighboring houses, Placer County officials said Monday.

The suspect was badly burned in the fire that destroyed his Auburn home during Sunday's hours-long standoff, making identification difficult, sheriff's Lt. John Poretti said.

The man had been drinking, arguing with relatives and sprayed his girlfriend with bear repellant before he began shooting with a handgun, shotgun and what sounded like a fully automatic weapon, Poretti said.

The weapons have not been recovered from the burned home, but buckshot pocked an armored vehicle used by a special enforcement team.

It has not been determined if the fire that began in the garage of the home about 35 miles northeast of Sacramento was started by the suspect or by tear gas fired in by authorities, Poretti said. But the resulting fire drove the suspect to a back door, where he was fatally shot by one of the deputies surrounding the home.

"The guy was going out the back door and shooting in the direction of that officer and others," Poretti said.
